their front'ends, as shown in Figs. 1, 3, and

14. This carriage is provided with wheels which travel in the ways or track formed by the flanges of the side rails of the swiveling base, as shown in Figs. '6 and 12. The rear portion of the carriage has a greater number of-these wheels to give a reinforced support therefor when the front portion is projected beyond the supportingerails of the base, as shown in Fig. 16. Standard-plates 31 and 32, having inclined upper edges, are mounted on opposite sides of the carriage and serve to support the loading mechanism hereinafter described. A stud 35, mounted midway of the cross-bar 36, serves as a bearing for-a pitman for reciprocating the carriage, as here inafter described.

A loading mechanism is mounted on the carriage and comprises an elevating shovcling conveyer provided at its lower front end with a wedge-like feeder 40, which is thrust under the coal or other material by the forward movement of. the carriage and operates on such thrust by a wedge-like action to cause such material to ride up over the feeder and drop from the higher rear ed e thereof onto the traveling mechanism of the elevating shoveling conveyer. supplemental feeder 50 may be used in connection with the feeder 40. The conveyer-frame is preferably divided into two parts an inclined lower front frame 60, carrying the feeder and preferablypivoted tokswing vertically to adjust the latter, to the plane of operation, and an upper inclined rear frame 70, supported on the standard-plates 31 and 32 of the carriage and forming a continuation of thelower frame 60. The side rails of the frame 70 are provided near their lowerends with hollow osses, as 7] .7 (shown in Fig. 7.3 which constitute the pivots for the swinging frame and .serve as bearings for the opposite ends of a transverse shaft, hereinafter described.

The side rails of the frames 60 and 70 are provided on their inner faces with longitudinal guideways, as 62 and 63 and 72 and 73, respectively, which serve as intermediate supapron of the conveyer. The-lower frame 66:1,

.is provided'with downward higs 62 and 63. having curved surfaces at thelr' rear ends concentric with the pivot of said frame and adapted to bear against the curved front ends of the side rails of the frame of the carriage '30, which are also concentric with said pivot. The frame 60 is provided with sideboards 64 and 65 and the frame with side boards 7 4 and 7 5, which-form the sides of a continuous trough for the upward passage of the coal or other material. The trough sides of the lowerframe 60 preferably terminate inside the trough sides of the upper frame 7 O. A transverse shaft 66 is supported in bearings near the front end of the front frame 60, and a transverse shaft 76 is supported in bearings near the rear end of the rear frame 70, and an endless conveyer-apron 61, preferably provided with flights 61, passes over sprocketwheels, as 67 and 77, disposed on said shafts,

and is further supported in the intermediate guideways 62 and 63 and 72 and 73. The forward part of this conveyer-apron preferably extends underneath the rear edge of the feeder 40, as shown in Fig. 1, so as to readily catch the material dropping off said feeder. Intermediate idle sprocket-pinions, as 68 and 69 on the front frame60 and as 7 8 and 79 on the rear frame 70,-serve to uide the conveyer-apron and permit the front frame to swing upward. The wedge-like feeder 40,

constitutes an inclined front extension of the inclined conveyer and may be rigidly connected with the frame thereof.

The supplemental feeder 50 preferably employedin connection with the feeder 40 to feed the material from the pile to the traveling mechanism of the elevating-conveyer, I I

may consist of a reciprocating wedge-like structure which moves up and down over the inclined upper face of the feeder 40, being connected at its opposite ends-.to the lower ends of slide bars or-shanks 51 and 52, having rack-teeth at their upper ends and sliding in boxes 53 and 54, mounted on opposite sides of the frame 60. This supplemental feeder has a beveled upper face to permit it to readily slide on its downstroke under the material over the face of the feeder 40 and an'abrupt rear'face to engage and push up said material over the top of the feeder 40 on its upstroke. The means for reciprocating this supplementalfeeder at the desired speed will be hereinafter described.

A supplerrentary elevating and delivery conveyer 80 for receiving the material from the primary conveyer and delivering it into the car or other receptacle or place for receiving it is preferably supported in fixed position on the car 10 and comprises an inclined 65 ports for the upper run of the endless fiighted to extend over the receiving-car and deed on any suitablev support on said car. The

support shown comprises two short forward posts 83, and 84, disposed, respectively, on

-the lateral -extension lland lateral projection 12 of theplatforrn of the car IOandcon- 'ne'cted by abridge-beam and two taller rear posts 86-and 87, .disposed on opposite sides at the rearof said platform. The posts .83 and 84 area sufficient distance apart to permit the base 20 to oscillate between them. The rear posts are connected near their lower end by a cross-bar 88. The horizontal rear extension 82 is braced to the inclined portion 81 by means of bridge-braces, as 89. The side rails of this secondary supplemental conveyer are provided with side plates 91 and 92, which form a trough for the conveyer, and these side plates are flared outward at the lower end of the conveyer, and-a hopper 93 is there formed to receive the material de-' livered from the primary conveyer60-70 when the latter is swung at a lateral angle to the car 10. A shaft 94 is ournaled in the forward end of the conveyer 80, and a shaft 95'is journaled at the. rear end thereof. The

shaft 94 carries idler sprocket-pinioha-as '96, and theshaft 95 carries driving sprocket-pinions, as 97. An endless apron 100, preferably provided with flights 101, passes over these sprocket-pinions. Idler sprocket-pinions, as 102 and 103, duplicated at opposite i gathering up sides of'the vconveyer-frame, guide the upper run of the endless apron, and sprocket-pinions, as 104 and 105, duplicated on opposite sides of the conveyef-frame, guide the lower run of said endless apron. Transverse bars? as" 99, are disposed underneath the hopper to prevent injury to the apron by any large umps of coal which'might drop thereonto,

Mechanical means are provided under the control of the operator for swinging} the front frame 60 upward when the machine is moved from place to place and for adjusting andlocking said frame at the angle best suited for material from a mine or other place- Sue nieansmay be thrown out of gear, whereby the pivoted shoveling-conveyer frame 60 may be unlocked and adapted to swing freely on the shoveling-stroke of the carriage to suit any inequalities of the The nweans shown for thispurpose. comprise a transverse shaft 106, supported; on standards 111 and 112,- mounted on the opposite side rails of the fixed conveyer-' frame 70.

States No. 731,371, dated June 16,

The 'operation% In the use of this machine p for loading coal in a mine the machine is run into the mine-room, by means of the minelocomotive or otherwise, where the coal has been shot down, the convey e'r 60 being swung upward, so that its casters ride on the nine-"track during this movement, as shown in Fig. 17. The machine-car is driven forward until the casters run off the 'end'of the track, and the frame 60 is then lowered to bring the feeder 40 on a plane just above the mine-floor in frentfof the pile of coal, as shown 'in 15; Then the car 10 is fastened in stationary position by the anchoring means shown in Fig. 2 or'other suitable means. The motor is connected with compressed-air main withinthe mine and the motive fluidturned on through. the controlling-lever 133. The lever 2161s shifted to bring the elevating mechanism ofv the. sup

'plemental conveyer. into operation? and the le'ver154 is also shifted to bring the ele I vating mechanism ofth'e' primaryconv'eyer 60 70 into operati0n.-*Tl1en the'lever 226-is operated to connect thecarriage-reciprocati .ing means: with the driving .mechanis'm, whereby the carriage 30 is thrust forward-t0 wardthe pile of coal into the position shown in Fig. 16, and then said mechanisms are dis connected by the back-shiftingof saidlever. In this forward movement of the carriage the feeder 40 slides under the coal and-causes the latter to ride up over the-inclinedxface of the feeder and drop over the rear edge thereof onto the endless apron 61 of-the primary con- ICO veye'r, whereby it is elevated anddelivered from the upper end of said primary 'conveyer onto the supplemental conveyer 80, which elevates and delivers it into the car or other receptacle or place of deposit,

In case the supplemental feeder 50 be employed the coal rldes over the forward wedgeshaped end thereof and falls onto thefeeder 40 on the forward movement of the carriage.

After ,the-carriageBO is moved forward a full stroke and the material has ceased tofall automaticallyover the rear end of the feeder 40 the coal disposed over the face of said feeder this supplemental feeder slides under the pile of coal and again pulls-up a load on the subsequent upstroke. The supplemental feeder continues to work until the mass of coal overlying the feeder 40 has been drawn up and'delivered onto the elevating mechanism of the conveyer. Then the lever 226 is operated to again shift the carriage reciproeating II1-( lianism into eration, and the carriage isdrawn back re'a y for another thrust.

Then the lever 260 is shifted and the swiveling base turnedto swing the feeder 4O slightly to one side or the other to give it anew position in front of the pile of coal. The carriage is then again thrust forward and the operation repeated. TliQbflSG is swiveled as far to one'side, then to the other, as may be necessary to clean up coal within the circle of the swing of the feeder. Then the anchors are removed from the car 10, and saidcar is moved forward'the proper distance to make another sweep of the coal. As a coal-car-is loaded it is hauled away and another put in place thereof. The coal-car may be shifted rearward to secure the delivery of the coal throughout the lengththereof, or the shifting of the car forward toward the pile may answer somewhatthis purpose.
